(FIRST PART ALREADY ANSWERED AND NEW PART ADDED) Why do you find the domain of both the numerator and denominator in a rational equation? When do you do it?

For example, if you had:   x-3 ------ 5x+3   you'd only find the domain and use the denominator. Why wouldn't you also do the numerator?    And then you'd use both the  numerator and the... more
